It's been 86 years since William P. Hobby Airport started welcoming passengers to its airfield. Though it's welcomed a few name changes and improvements throughout the decades, the changes currently underway may just be the airfield's most exciting yet.

On the horizon, passengers can expect an additional parking garage, roadway modifications, new concourse and an expanded terminal, all of which will help accommodate international flights to and from Houston.

The expanded terminal will make room for a new ticket counter, six additional security checkpoints, five new gates and a Federal Inspections Services facility for Customs and Borders Protection. Together, the upgraded facility will allow for 400 to 800 additional passengers to travel through Hobby during peak hours.

Hobby's upgrades are expected to cost Southwest about $150 million. Groundbreaking started in May 2013 and is slated to wrap up by September 2015.
